Slove : 28/36 = 14/y

Dafna1 [17]

Answer:

y = 18

Step-by-step explanation:

<h3>i) reduce the fraction with 4</h3>

$\frac{28}{36} = \frac{14}{y}$

$\frac{28 \div 4}{36 \div 4} = \frac{14}{y}$

$\frac{7}{9} = \frac{14}{y}$

<h3>ii) simplify the equation with cross multiplication</h3>

$\frac{7}{9} = \frac{14}{y}$

$7y = 14 \times 9$

$7y = 126$

<h3>iii) divide both sides of the equation by 7</h3>

$\frac{7y}{7} = \frac{126}{7}$

$y = 18$
